[Haskell-cafe] Using Intero on latest MacOS

I’m using the latest developer beta of MacOS High Sierra. There are some problems with new Clang/LLVM; I can’t install terminfo, because of this problem: https://ghc.haskell.org/trac/ghc/ticket/13805 https://ghc.haskell.org/trac/ghc/ticket/13805. It seems it's been already fixed (and that it can be fixed by passing an argument to CFLAGS) - I don’t really know what CFLAGS are, though, and I also don’t know how can I update my local Clang/LLVM to include the new patch. Is somebody in a similar situation? I’d welcome any help.
